Product use:
Sponge compression fatigue testing machine, this machine is used to determine the concave hardness of porous elastic materials. The polyurethane foam sample can be tested according to the national standard, and the compressive hardness of sponge, foam and other materials can be accurately measured. In addition, it can also be used to measure the specified compression hardness of the seat foam (such as backrest, seat cushion foam, etc.), and accurately measure the compression hardness of each foam part of the seat.
Test principle:
The sponge foam compression stress test puts the sample between the upper and lower pressure disks, and when the upper pressure disks compress the sample of A certain size down to the concave degree specified by the A method (B method, C method) required by the national standard at the specified speed, the load element on the load cell will feedback the induced pressure to the controller for processing and display, so as to measure the collapsibility hardness of the sponge, foam and other samples.
Functional features:
1. Automatic zero clearing: After the computer receives the test start instruction, the system automatically clears zero.
2, automatic return: after the sample is broken, it will automatically return to the initial position.
3, automatic shift: according to the size of the load, you can switch different gears to ensure measurement accuracy.
4, change the speed: The machine can change the test speed arbitrarily according to different samples.
5, indicating value verification: the system can achieve the accurate calibration of force value.
6, control method: According to the test needs can choose the test force, test speed, displacement, strain and other test methods.
7, a multi-purpose machine: equipped with different specifications of sensors, can achieve a multi-purpose machine.
8, curve traversal: After the completion of the test, the mouse can be used to find the test curve point by point force value and deformation data and analysis.
9, display: data and curve test process dynamic display.
10. Results: The test results can be accessed and the data curve can be analyzed.
11, limit: with program control and mechanical limit.
12, overload: automatic stop when the load exceeds the rated value.
